To see the ace in the deck of cards, suggests ambiguity in your life. You need some clarity. In particular, the ace of hearts means that you are involved in some love affair. If you see the ace of spades in your dream, then it means that you are involved in a scandal. If you see the ace of diamonds, then it symbolizes your legacy. And if you see the ace of clubs, then it indicates that you will be involved in some legal matter. Alternatively, the dream may be a metaphor that you are an "ace". Or the dream is a pun on "acing" a test.
